New Sale of Sponsorship Rule - Due to some issues with blurred lines in the rule set regarding team ownership and conflicts of interests, Riotamended their ruleset to allow for more clarity. The TL;DR is below is taken directly from Lolesports:

We’re instituting a new policy to better distinguish between LCS team owners, brand owners, and those who sell sponsorships for LCS teams to uphold competitive integrity and prevent conflicts of interest.

Those selling sponsorships on behalf of LCS teams will no longer be able to also own LCS team branding.

2014 LCS teams Evil Geniuses and Alliance will be playing under different brands (names, logos, etc.) next season.

GoodGame Agency, which currently sells sponsorships on behalf of both teams, will continue to do so.

Riot also recently amended their rules to allow for coaches to be present on stage during the champion select portion of the game among a variety of other changes. The TL;DR of the changes is below:

We’re leveling up our support of coaching in the LCS.

Head Coaches will now be officially recognized as LCS team members.

Each team will be provided monetary support to shore up their ability to attract and retain a quality Head Coach and coaching staff.

LCS Head Coaches will now be subject to behavioral checks, required to attend their teams’ matches in person, and held to the highest standard of conduct in and out of game.

LCS Head Coaches will now be on-stage and able to communicate with their players during the pick-ban phase.

Riot also recently announced a change to their eSports banning policies to allow for reform instead of just permanently banning people. TL;DR is below:

We want disciplinary action to be about reform as well as punishment.

We are introducing a new framework for long-term bans and permabans that treats all bans as suspensions subject to periodic review. More details on the timing and criteria for this review are available below.
